O Clavis David or "O Key of David" was a natural choice of Antiphon for me for the Choral Arts Philadelphia's Holiday "O Antiphon" commissioning project. On top of the namesake bit, the key of David is mentioned in Revelation 3:17 at the church of Philadelphia (but in Turkey, not Pennsylvania).

The words of O Clavis David resonate today as much as they have in the previous millennia:

"O Key of David, and the scepter of the House of IsraelWho open, and no one shutsWho shut, and cannot be openedCome, and lead those in bondage out of prison,Who stay in darkness, and the shadow of death"

It is a call to the Messiah; an inextinguishable light in the darkesttimes, who leads us from the suffering of war into the bounty of peace.
